Radical polymerization of styrene gives a linear polymer. Radical polymerization of a mixture of styrene and 1,4-divinylbenzene gives a cross-linked network polymer of the type shown in Figure 29.1. Show by drawing structural formulas how incorporation of a few percent of 1,4-divinylbenzene in the polymerization mixture gives a cross-linked polymer.
Polymerization of 1 3 -hexadiene can yield in either cis (Z) or trans (E) polymer.on the other hand the polymerization of 1 4 -hexadiene will not have any isomer.Why?
4 Draw out the atom transfer radical polymerization (ATRP) of styrene utilizing CuBr-PMDETA as the catalyst. Include the initiation and propagation steps.
Identify the repeating unit in the polymer formed from the following reaction sequence. C=C-O-C=O ---->1] Benzoyl peroxide 2] NaOH, H2O, heat | C *The hanging carbon is attached to carbon above it, with the oxygen double bond. I know that the answer should be a repeating sequence of two carbons with an -OH hanging off them but i dont follow the mechanism. Sorry for the confusing molecule structure, there isnt a good way to draw on this platform.
Reaction (blank) Choose your answer here in the radical polymerization of styrene would afford the more stable radical intermediate. A) 1 B) 2 C) 1 or 2
(a) Show how poly(propylene oxide) can be synthesized via anionic ring-opening polymerization. (b) Draw the mechanism for the initiation and first two propagation steps.
Draw mechanism (with electron pairs, flow of electrons, charges, and steps, where applicable) of radical polymerization of styrene initiated by nitrile type initiator (RN=NR) that consists of initiation (two steps), propagation, and two termination steps (when two chains undergo combination and disproportionation reactions) Im stuck on how to show the mechanism for the two termination steps
Show the differences between the chain-growth and step-growth mechanisms of polymerization.
Use curved arrows to show mechanism of reaction, show initiation, propagation, and termination.
Show the chain reaction (initiation ,propagation and termination) step in a polymer known as PMMA .
Use mechanisms to show how monomers polymerize under acidic, basic, orfree-radical conditions. For chain-growth polymerization, determine whether the reactive end is more stable as a cation (acidic conditions), anion (basic conditions), or free radical (radical initiator). For step-growth polymerization, consider the mechanism of the condensation.
What small molecule is generated during the polymerization in the above molecule?
